On Sunday, February 22, South Korea will experience unusually warm temperatures, with the daytime high reaching around 20 degrees Celsius across much of the nation. The Korea Meteorological Administration forecasts that while the day will start mostly cloudy, the southern regions and Jeju Island will begin to clear up in the afternoon, followed by a clearer night for the central areas. Expected rainfall remains minimal, with less than 5mm predicted in several inland areas, including Seoul and Gyeonggi Province.

Despite the warm daytime temperatures, morning lows will vary from -2 to 13 degrees Celsius, creating a notable contrast. Cities like Seoul will start around 9 degrees, with other regions also experiencing mild early temperatures. The highest daytime temperatures recorded across the country are among the highest so far this year, with notable highs being 21.3 degrees in Gangneung and 20.3 degrees in Gyeongju. The warm spell will be short-lived, however, as forecasts indicate a drop by 3 to 8 degrees on February 23, accompanied by a significant cold snap with temperatures plummeting to as low as -7 degrees Celsius.

The report also highlights that fine dust levels will reach unhealthy levels across all regions in the afternoon, impacting air quality. This weather change emphasizes the ongoing fluctuations in the seasonal climate and raises concerns about air pollution that could affect public health, especially following a brief warm respite during this winter season.
